APPARATUS FOR TREATING ARTICLES WITH X-RAYS.

Application filed May as, 1909. Serial No. 493.995.

To all whom it may concern:

Be itknown that I, FRANKLIN S. SMITH, a citizen of the United States, residing in Philadelphia, county of Philadelphia, State of Pennsylvania, have invented a certain new and useful Apparatus for Treating Articles with X-Rays, of which the following is a specification.

I have found that destructive insects which infest various articles of commerce, such, for instance, as tobacco, furs, woolens, etc, may be destroyed by treating such articles with X-rays or their equivalent, and I have also found that not only may such insects or bugs be destroyed but that the eggs, larvae and pupae of such insects or bugs may also be destroyed by treating such articles with. X-rays.

The object of. my invention is to provide an apparatus for treating articles of commerce of whatever size or shape with X-rays in a practical and commercial manner.

The objects, purposes and advantages of my invention will appear more fully from the detailed description of my invention which follows.

One form of a convenient embodiment of my invention is illustrated in the accompanying drawing forming a part of th1s specification, but it will be understood that changes in the details of construction and arrangement may be made within the scope of the claim without departing from my invention.

Referring to the. drawings: Figure I is at top plan view of a construction of apparatus embodying my invention; and Fig. II

"is a vertical section of'the same.

In the drawings I have shown an apparatus which may be employed for the purpose of carrying articles of commerce into such relation to a source of radiant energy as to bring the same within the action or influence of the rays emanating from such source. In the construction shown in-these figures, I have provided a leaden cylindrical hollow structure 27 or its equivalent having a wooden top 27 and within which is supported a vertical shaft 28 journaled in bearings 29 and 30. Upon this shaft a supporting platform 32 is secured. The shaft and the platform carried therebyare driven from a motor shown conventionally at 33. The motor shaft 34 is provided with a bevel gear which engages a bevel gear 36 on the upright shaft 28. The source of radiant energy in the construction shown consists of an X-ray tube 38 having an anode 39 and a cathode 40. 41 designates wires extending from the anode and cathode to a. source of high potential electrical energy which is not shown.

The anode 39 is arranged at an angle of about 4:5 degrees to the line of travel of the articles carried-by the supporting platform Patented May 5, 1914."

32 so that the rays extend principally in a direction transversely of theline of travel of such articles.

A portion of the cylindrical structure 27 is cut away, as indicated at 43, in order to provide a space to permit the placing of the articles upon the platform 32 to be carried into operative relation to the X-ray tube 38. It will be observed that the arrangement of the parts is such that the articles to be treated may be placed upon the supporting platform 32 without the necessity of extending the hands of an attendant or workman into the range of action of the X-rays.

In the construction illustrated, I have provided a source of radiant energy, consisting in the construction shown of an X- ray tube, so combined and related to other parts of the apparatus as to provide means by which articles may be conveniently and economically carried and supported in proper relation to the said tube so as to subject such articles to the action of the rays emanating from the said source.

Having thus described my invention, I claim The combination of a cylindrical hollow structure having an opening formed therein, an X-ray tube located in the said cylindrical structure, a rotatable vertical shaft supported in the said cylindrical structure, means for occasioning rotation of the said shaft, acarrying 01 supporting table secured In testimony that I claim the foregoing t0 the said shaft and projecting into The as my invention, I have hereunto signed my said opening, the said table being adapted name this 27th day of May, A. D. 1909.

to support articles placed thereon and toi FRANKLIN S. SMITH. carry them into position to be acted upon In the presence 0fby the my: en'mnat-ing from the said X-ray S. SALOME BROOKE,
